为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不设置为限定本申请。
相关技术中，耳机是一种电声换能器，其通过将电信号转换成声音信号从而将待播放的音频播放出来。耳机根据换能方式可分为动圈式耳机、动铁式耳机、圈铁耳机和等磁式耳机等。其中，圈铁耳机是将动圈式耳机、动铁式耳机相互结合的一种耳机。圈铁耳机具有动圈单元以及动铁单元，在组装圈铁耳机时，通常是将动圈单元以及动铁单元分别组装到圈铁耳机的外壳内，如此，导致圈铁耳机的组装过程比较复杂，组装效率较低。且动圈单元以及动铁单元均安装到外壳内，导致壳体的体积变大，最终导致圈铁耳机的整体体积变大。
为解决上述技术问题，如图1所示，本申请实施例第一方面提供一种圈铁喇叭组件10，圈铁喇叭组件10包括动圈喇叭11、动铁喇叭12以及弹性件13。
动圈喇叭11设置为发声，且动圈喇叭11相比于动铁喇叭12具有更好的低音效果。将动圈喇叭11的朝向动铁喇叭12的方向作为动圈喇叭11的发声方向。动圈喇叭11在发声方向上靠近动铁喇叭12的一侧具有容置槽1111，容置槽1111设置为容置至少部分动铁喇叭12，从而使得动圈喇叭11与动铁喇叭12堆叠得更为紧凑，有利于圈铁喇叭组件10的小型化。
动铁喇叭12设置为发声，且动铁喇叭12相比于动圈喇叭11具有更好的中高音效果。本申请实施例的圈铁喇叭组件10，同时包括动圈喇叭11以及动铁喇叭12，兼具动圈喇叭11的低音效果以及动铁喇叭12的中高音效果，在动圈喇叭11发出的低音与动铁喇叭12发出的中高音混响后，可以获得更好的音质。动铁喇叭12位于动圈喇叭11的发声方向上，且动圈喇叭11与动铁喇叭12同轴设置。动圈喇叭11与动铁喇叭12同轴设置可以理解为：在动铁喇叭12与动圈喇叭11组装完成后，动铁喇叭12的中轴线与动圈喇叭11的中轴线共线。动圈喇叭11与动铁喇叭12同轴设置，相比于动圈喇叭11与动铁喇叭12错位设置(也即动铁喇叭12的中轴线与动圈喇叭11的中轴线不共线，而是平行或者相交)，可以使得圈铁喇叭组件10的整体体积更小，且更规整，因此，设置为安装圈铁喇叭组件10的壳体的体积也可以更小，对应于更规整的圈铁喇叭组件10，壳体也更加易于生产制造。
在动圈喇叭11的发声方向上，动铁喇叭12具有相对的安装端121以及出音端122，其中，安装端121相比于出音端122更靠近动圈喇叭11，且至少安装端121容置于容置槽1111内，也即，动铁喇叭12的至少部分结构容置于动圈喇叭11中，如此，在动圈喇叭11的发声方向上，可以使得圈铁喇叭组件10的尺寸变小；出音端122具有发声孔1221，动铁喇叭12可以经由出音端122的发声孔1221向动铁喇叭12外部发声，动铁喇叭12的发声方向可与动圈喇叭11的发声方向相同，从而使得动圈喇叭11发出的低音以及动铁喇叭12发出的中高音更多地在动铁喇叭12的前方混响，避免分频输出各个频段声波支离破碎的劣势，可以获得自然一体、清晰且有层次的听感。
可以理解的是，如果动铁喇叭12体积较小，动铁喇叭12整体也可以容置于容置槽1111内，也即，动铁喇叭12的安装端121以及出音端122均容置于容置槽1111内，从而使得圈铁喇叭组件10在发声方向上的尺寸更小。
弹性件13具有弹性，且弹性件13的至少一部分设于容置槽1111中，弹性件13分别与容置槽1111的槽壁以及安装端121过盈配合，也即，弹性件13的外侧抵接于容置槽1111的槽壁并与容置槽1111的槽壁过盈配合，同时，弹性件13的内侧抵接于安装端121并安装端121过盈配合，如此，在保证圈铁喇叭组件10具有较小体积的基础上，可以实现动圈喇叭11与动铁喇叭12之间的快速组装及固定。
动圈喇叭11与动铁喇叭12的组装过程可以是：先将适配形状的弹性件13(例如横截面为U形或L形、矩形等)安装于容置槽1111中，再将动铁喇叭12的安装端121通过外力插入容置槽1111中，从而实现弹性件13分别与容置槽1111的槽壁以及安装端121的过盈配合；也可以是：先将安装端121插入容置槽1111中，再将适配形状的弹性件13(例如横截面为矩形等)塞入安装端121与容置槽1111的槽壁之间，从而实现弹性件13分别与容置槽1111的槽壁以及安装端121的过盈配合；还可以是：先将安装端121与适配形状的弹性件13进行组装，再将组装后的安装端121以及弹性件13一齐插入容置槽1111中，从而实现弹性件13分别与容置槽1111的槽壁以及安装端121的过盈配合。无论哪种组装方式，动圈喇叭11与动铁喇叭12的组装过程均较为简便，组装效率更高；在将圈铁喇叭组件10安装于耳机壳体内时，只需将组装后的动圈喇叭11、动铁喇叭12以及弹性件13放入壳体即可，这一组装过程也较为简便，同样可以提高组装效率。可以理解的是，圈铁喇叭组件10不限于应设置为耳机，也可以应设置为其他听音设备如助听器等。
可以理解的是，弹性件13的材质、尺寸、数量以及形状可以不做限制，只需能够实现弹性件13分别与容置槽1111的槽壁以及安装端121过盈配合即可。对于材质，例如，弹性件13的材质可以为硅胶、TPU(Thermoplastic polyurethanes，热塑性聚氨酯弹性体橡胶)或者TPE(Thermoplastic rubber，热塑性弹性体)等；对于尺寸，例如，弹性件13的最大径向尺寸可比容置槽1111径向上的尺寸略大，以在弹性件13放入容置槽1111内而安装端121未放入容置槽1111内时，弹性件13本身可以与容置槽1111的槽壁过盈配合，但是并不以此为限，例如，在安装端121插入容置槽1111后，安装端121与容置槽1111之间存在间隙，弹性件13的尺寸只需大于该间隙，即可保证弹性件13放置于容置槽1111内时，弹性件13分别与容置槽1111的槽壁以及安装端121的过盈配合；对于数量和形状，弹性件13的数量可以为一个或者多个，在弹性件13的数量为一个时，弹性件13可以为环状，并套设于安装端121，从而增大弹性件13与安装端121以及容置槽1111的槽壁接触面积，提高动圈喇叭11、动铁喇叭12以及弹性件13三者之间的连接稳定性；在弹性件13的数量为两个或者两个以上时，多个弹性件13可以为块状或者弧状，多个弹性件13可以等间距设置于安装端121与容置槽1111的槽壁形成的间隙中，从而提高安装端121受力的均匀性，进而提高动圈喇叭11、动铁喇叭12以及弹性件13三者之间的连接稳定性。
如图2至图4所示，进一步地，弹性件13可以具有嵌设槽131，安装端121的至少一部分设于嵌设槽131中，通过弹性件13包裹安装端121，从而增大弹性件13与安装端121的接触面积，且安装端121与嵌设槽131的槽壁过盈配合，从而可以提高弹性件13与安装端121的连接稳定性。此外，由于安装端121与弹性件13过盈配合，安装端121挤压弹性件13，从而使得弹性件13与容置槽1111的槽壁抵接且过盈配合，同样可以增大弹性件13与容置槽1111的槽壁的接触面，从而可以提高弹性件13与动圈喇叭11的连接稳定性。
请参考图2，具体地，弹性件13可以包括依次连接的底部132、周侧部133以及开口部134。底部132具有嵌设槽131的槽底，底部132可以与容置槽1111的槽底抵接；周侧部133具有嵌设槽131的槽壁，且周侧部133被夹持于安装端121与容置槽1111的槽壁之间， 并与安装端121以及容置槽1111的槽壁过盈配合；开口部134具有嵌设槽131的槽口，安装端121可经由嵌设槽131的槽口拆入嵌设槽131中，从而使得安装端121与嵌设槽131的槽壁过盈配合。
进一步地，弹性件13还可以具有一个或者多个通槽135，通槽135贯穿周侧部133或底部132，且通槽135与嵌设槽131连通，通过开设通槽135，在对动圈喇叭11、动铁喇叭12以及弹性件13进行组装时，可以使得弹性件13更易于发生形变，例如，在将弹性件13装入容置槽1111时，由于通槽135的存在，弹性件13具有更多的形变空间，因此，弹性件13更易于发生形变，同理，在将安装端121转入弹性件13的嵌设槽131时，由于通槽135的存在，弹性件13具有更多的形变空间，因此，弹性件13更易于发生形变。通槽135可以有多个，多个通槽135之间间隔设置，多个通槽135可以使得弹性件13具有更多的形变空间，更易于发生形变。可以理解的是，通槽135可以只贯穿底部132或者周侧部133，通槽135也可以替换成盲槽，盲槽不与嵌设槽131连通，盲槽可以单独开设于周侧部133或者底部132，也可以同时开设于周侧部133或者底部132。
请参考图3和图4，圈铁喇叭组件10还包括反馈麦克风14以及柔性电路板15，反馈麦克风14可设置在圈铁喇叭组件10上或其附近。进一步地，弹性件13还具有安装槽136，反馈麦克风14安装于安装槽136内。柔性电路板15与动圈喇叭11、动铁喇叭12以及反馈麦克风14均电性连接。反馈麦克风14安装于安装槽136内，不仅安装方便，且不额外占用空间，反馈麦克风14设置为采集环境噪音，并将采集到的环境噪音信号通过柔性电路板15传送给与圈铁喇叭组件10连接的处理器，该处理器可以是耳机的处理器，也可以是与耳机电性连接的音频播放终端的处理器，处理器进行实时运算，通过柔性电路板15向动圈喇叭11以及动铁喇叭12发送与环境噪音相位相反、振幅相同的音频信号，并通过动圈喇叭11以及动铁喇叭12将音频信号对应的声音播放出来，以抵消环境噪音，从而达到主动降噪的效果。柔性电路板15具有配线密度高、重量轻、厚度薄、弯折性好的特点，可以根据实际情况进行弯折布线，从而使得通过一个柔性电路板15同时实现与动圈喇叭11、动铁喇叭12以及反馈麦克风14之间的电性连接。
如图4所示，具体地，动圈喇叭11包括支撑件111以及喇叭本体112，支撑件111具有容置槽1111，喇叭本体112设置于支撑件111上，借助支撑件111可以提高喇叭本体112在壳体内安装的稳定性，进而提升圈铁喇叭组件10结构的稳定性。可以理解的是，喇叭本体112的内部可以为支撑件111留有容纳空间，使得支撑件111全部或部分收容于容纳空间内，进而使得支撑件111与喇叭本体112组装得更加紧凑，有利于圈铁喇叭组件10的小型化。
更具体地，喇叭本体112包括振膜1121、环形音圈1122以及环形磁铁1123，振膜1121可以通过振动发出声音，振膜1121的边缘可以与环形磁铁1123连接；环形音圈1122与振膜1121的朝向支撑件111的一侧表面连接；环形磁铁1123与环形音圈1122同轴设置，环形磁铁1123与环形音圈1122均位于振膜1121的同一侧。可以理解的是，环形磁铁1123呈中空的环状，使得环形磁铁1123可以合围形成一容置空间，支撑件111可以部分或整体设置于容置空间内，进而使得开设于支撑件111上的容置槽1111也部分或全部位于容置空间。
环形音圈1122可以为线圈，当通入环形音圈1122的电流发生改变时，环形音圈1122所产生的磁场随之改变。环形磁铁1123可以为永磁铁，能够产生永磁场。当环形音圈1122产生的磁场发生变化时，环形磁铁1123的永磁场与环形音圈1122产生的磁场相互作用，使得环形音圈1122在其轴向上往复振动，继而可以通过环形音圈1122带动振膜1121往复振动，从而实现喇叭本体112的发声功能。
更进一步地，本申请实施例将振膜1121的设置有环形音圈1122的一侧表面朝向支撑件 111设置，也即，振膜1121的设置有环形音圈1122的一侧表面朝向动铁喇叭12设置，振膜1121采用其设置有环形音圈1122的一侧(或称背面)作为发声位置(或称背面发声)，如此，使得动铁喇叭12更靠近振膜1121的发声位置，能够减小动铁喇叭12和振膜1121两者所输出的声音的相位差异，进而改善耳机1的音质。
请继续参考图4，具体地，支撑件111包括支撑部1112以及容置部1114。支撑部1112呈环状设置，容置部1114与支撑部1112的内环边缘连接，容置部1114开设有容置槽1111，容置槽1111的槽口朝向动铁喇叭12设置，环形磁铁1123设置于支撑部1112上并环设于容置部1114外侧，以通过支撑部1112支撑环形磁铁1123，也使得容置部1114嵌入环形磁铁1123中，支撑部1112具有动圈喇叭11的出音孔1113，振膜1121振动产生的声音经由出音孔1113向动圈喇叭11外部传送，由此可以使动圈喇叭11发出的低音与动铁喇叭12发出的中高音进行混音，使得圈铁喇叭组件10发出的声音更加立体。可以理解的是，出音孔1113的数量、大小、位置以及分布方式可以根据实际情况进行设置，本实施例对此不做限定。且为了使振膜1121振动产生的声音经由出音孔1113传出，本实施例除了将出音孔1113开设于支撑部1112，以避免出音孔1113开设于容置部1114时被动铁喇叭12封堵，且环形磁铁1123也应当避开出音孔1113，以避免环形磁铁1123封堵出音孔1113。
由于动铁喇叭12的安装端121收容于容置槽1111中，且环形磁铁1123环设于容置部1114外侧，加之至少安装端121收容于容置槽1111中，因此，安装端121实际收容于环形磁铁1123中，也即，动铁喇叭12部分收容于动圈喇叭11中，如此，可以使得动铁喇叭12与动圈喇叭11堆叠得更加紧凑，有利于圈铁喇叭组件10的小型化。
如图5所示，更进一步地，动圈喇叭11还包括喇叭后盖113，喇叭后盖113设置于振膜1121的背离环形磁铁1123的一侧，喇叭后盖113的边缘与环形磁铁1123及/或振膜1121的边缘连接，可以理解的是，喇叭后盖113盖合于喇叭本体112，可以对喇叭本体112起到保护作用，具体而言，可以对环形磁铁1123、振膜1121以及环形音圈1122等部件进行保护。具体地，振膜1121设置于喇叭后盖113与环形磁铁1123之间，振膜1121的边缘可与环形磁铁1123单独连接，也可与喇叭后盖113单独连接，还可以与环形磁铁1123以及喇叭后盖113均连接，如此，可以提高喇叭本体112与喇叭后盖113的连接稳定性。
请参考图5，具体地，喇叭后盖113具有调音孔1131，圈铁喇叭组件10还包括声学网布16，声学网布16罩设于调音孔1131，调音孔1131处设置的声学网布16，不仅可以防止外部杂物进入动圈喇叭11内，而且可以通过更换不同目数的声学网布16调整圈铁喇叭组件10的声音输出曲线。此外，还可以在出音孔1113上也罩设一层或多层声学网布16，从而使得振膜1121振动产生的声音经由出音孔1113调整后向外部传送。
如图4-5所示，进一步地，为了提高喇叭本体112的安装稳定性，环形磁铁1123的一端可以与支撑件111的支撑部1112密封连接，环形磁铁1123的另一端可以与喇叭后盖113密封连接。可以理解的是，前述的“密封连接”可以理解为：两个部件连接且两个部件在连接位置处密封，从而使得支撑件111、振膜1121、环形音圈1122环形磁铁1123以及喇叭后盖113形成一个密封的动圈喇叭模组，只通过出音孔1113以及调音孔1131与动圈喇叭模组外部连通，如此，在将圈铁喇叭组件10安装于耳机壳体时，可以避免将支撑件111、振膜1121、环形音圈1122、环形磁铁1123、喇叭后盖113以及动铁喇叭12逐个安装到壳体内，从而更易于实现对圈铁喇叭组件10与耳机1的壳体的组装，提高圈铁喇叭组件10与耳机1的壳体的组装效率。
如图6所示，本申请的第二方面还提供一种耳机1，耳机1包括上述的圈铁喇叭组件10以及可收容圈铁喇叭组件10的壳体20，壳体20具有出音口21，动铁喇叭12的出音端122朝向出音口21的方向设置。
壳体20的形状、材质以及尺寸可以不做限制，例如，壳体20具有出音口21，沿靠近 出音口21的方向，壳体20的径向尺寸逐渐减小，如此，可使得壳体20在包含圈铁喇叭组件10的情况下，还可以具有较小的外形结构，进而缩小耳机1的整体尺寸。再如，壳体20可以为塑料材质或金属材质，塑料材质易于成型，且成本低廉；金属材质则可以提高壳体20的整体刚性，可以避免壳体20轻易受到损伤，也可以对壳体20内部的零部件起到更好的保护作用。
壳体20的内壁上可以设置有定位台阶22，以使喇叭后盖113的边缘抵接于定位台阶22，在组装时可以方便地将喇叭后盖113组装于定位台阶22上，且喇叭后盖113组装于定位台阶22后，通过定位台阶22承载喇叭后盖113以及与喇叭后盖113连接的喇叭本体112，可以提高喇叭本体112以及喇叭后盖113的安装稳定性。
进一步地，为进一步提高喇叭后盖113在壳体20上的安装稳定性，还可以在喇叭后盖113的边缘以及壳体20的内壁中的一个设置有凸起，喇叭后盖113的边缘以及壳体20的内壁中的另一个设置有卡槽，以使凸起与卡槽卡接，进而使得喇叭后盖113的边缘与壳体20的内壁通过凸起以及卡槽卡接，此设计不仅方便喇叭后盖113与壳体20之间的组装，且组装后，喇叭后盖113不能相对于壳体20转动，从而提高喇叭后盖113在壳体20上的安装稳定性。
本申请实施例提供的耳机1，通过在壳体20内设置具有上述结构的圈铁喇叭组件10，使得动圈喇叭11和动铁喇叭12之间的堆叠结构更小，可以缩小壳体20的尺寸，进而可以缩小耳机1的整体尺寸；借助设置在耳机1内的反馈麦克风14和圈铁喇叭组件10，能够实现在包含圈铁喇叭组件10的耳机1上的主动降噪；将动铁喇叭12的出音端122朝向出音口21设置，动铁喇叭12发出的中高音与动圈喇叭11发出的低音在出音口21处产生混响，并通过出音口21进入人耳，从而使得耳机1具有更好的音质。
本实施例的附图中相同或相似的标号对应相同或相似的件件；在本申请的描述中，需要理解的是，若有术语“上”、“下”、“左”、“右”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此附图中描述位置关系的用语仅设置为示例性说明，不能理解为对本专利的限制，对于本领域的普通技术人员而言，可以根据具体情况理解上述术语的具体含义。
以上仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
